Google rolled out a “Conversions with cart data diagnostics” tool to help advertisers spot and fix issues in their cart data setup. This is an enhanced form of conversion tracking that logs item-level details like ID, price, and quantity.
Why we care. Accurate cart data powers richer sales insights, sharper optimization, and stronger ROI for campaigns, but incomplete or mismatched data can lead to underreporting and poor targeting.
How it works:
Checks if cart data is sent with every purchase conversion.
Verifies product details are complete.
Confirms item IDs match Merchant Center listings.
Health check. The tool grades setups as Excellent, Good, Needs attention, or Urgent, with alerts guiding fixes to keep data quality high and campaigns running at full potential.
Bottom line. Advertisers who rely on product-level conversion tracking should use the new diagnostics tool to catch data errors early, protect reporting accuracy, and ensure campaigns get the full benefit of Google Ads’ optimization features.
